Benefits of technology

The invention aims to increase the economic efficiency of a fuel cell system by incorporating a voltage converter device and a load voltage converter, as well as an additional voltage converter. These parts are easily assembled and cost-effective. Additionally, the invention allows for the temperature of the fuel cell to be regulated by directing air from a bypass line through a residual gas heat transfer device and an additional heat transfer device, which can be controlled to heat or preheat the fuel cell air. The heat transfer devices can be bypassed to reduce or limit the temperature of the fuel cell, should it become overheated. This is made possible with the help of a bypass line that connects the bypass air line to the fuel cell air line between the two heat transfer devices.

Problems solved by technology

Since the fuel cell during a starting operation of the fuel cell system cannot provide electrical energy directly, the fuel cell system during the starting operation requires an external energy supply for supplying the system loads.

Embodiment Construction

[0062]Referring to the drawings in particular, FIG. 1 shows an arrangement 0 having a fuel cell system 1, which can be arranged in a motor vehicle or in any other mobile or stationary application as a sole or additional electrical source of energy, with a fuel cell 2 and a residual gas burner 3. The fuel cell 2 during operation generates electric current from anode gas and cathode gas, which can be tapped off via electrodes 4. The fuel cell 2 is preferably configured as a SOFC-fuel cell. The residual gas burner 3 during operation converts anode exhaust gas with cathode exhaust gas, generating burner exhaust gas in the process. The conversion in this case can be effected with an open flame. A catalytic conversion is likewise conceivable.

[0063]An anode exhaust line 5 connects an anode side 6 of the fuel cell 2, which comprises at least one anode 95, to the residual gas burner 3. A cathode exhaust line 7 connects a cathode side 8 of the fuel cell 2, which comprises at least one cathode...

Abstract

A system (0) includes an electrical load system (54) with a load network battery (82), and a fuel cell system (1). Operation is simplified, especially during start of the fuel cell system (1) if the fuel cell system (1) has a system battery (56). A system voltage across the system battery (56) can be supplied to electrical system loads (80) of the fuel cell system (1) and, via a load voltage converter (77) and at least one additional voltage converter (86), to the load system (54) and secondary electrical loads (84, 85).
